2.6.2 PLL_MUX[3:0] -- Multiplexer Control for LD Pin
These bits set the output mode of the LD pin. The table below lists several different modes.
2.6.3 POWERDOWN bit -- Device Power Down
This bit can power down the device. Enabling this bit powers down the entire device and all blocks, regardless of the state of any
of the other bits or pins.
2.6.4 EN_CLKout_Global bit -- Global Clock Output Enable
This bit overrides the individual CLKoutX_EN bits (See 2.3.5). When this bit is set to 0, all clock outputs are disabled, regardless
of the state of any of the other bits or pins. See 1.8 for more information on CLKout states.
2.6.5 EN_Fout bit -- Fout port enable
This bit enables the Fout pin.
